Noctua NF-A20 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (200x30mm, Black)

I bought this fan to replace a failing Cooler Master A20030-10CB fan that was mounted to the top of my Cooler Master HAF 922 case. It turns out the presence of 170mm mounting points on this fan prevent it from fitting into this particular case, which uses 154mm hole spacing. I did not know this before I bought the fan. Nothing some marking and quick Dremeling couldnt solve, though! Now that the fan is in the case I love it. Almost silent and moves a lot of air. Huge improvement over the fan I removed, although that one was 8 years old. Well see how this one holds up.

Replaced my TT 200MM case fans and bought these to match the other noctua products. Its quiet at max rpm of 800 and you can feel that it is pulling/pushing a lot of air through.

I bought this to replace a top 200mm fan on my PC case, but the side by side comparison between this and a 10+ year old fan showed the Noctua moved significantly less air at 100% power despite being a bit quieter. Will return & buy a different brand with a higher CFM.

I purchase a lot of Noctua fans for building high-end computers, so wanted to try these out. On the plus side, they are silent and come with the necessary black sound/vibration pads. On the minus side, they move a bit less air than I had expected (perhaps I am just too used to the industrial line) and the price is a bit too high. There are cases where this would be great and I can say that these are better quality than many fans of a similar size. Buy these if you need a fan of this size, but note that a couple Noctua industrial 140 fans will move more air if that is what you are looking for.

This absolute bohemith of a fan works quietly, but pushes an astronomical amount of air through. The build quality is amazing (as expected) since its a Noctua product. I expect this bad boy to run for a long time, currently using it on one of my servers.

Exactly what I needed for my audio video receiver.

I bought a new Cougar case because it had a solid side panel with a perforated inlet for a 200mm fan. My system is air cooled. However, the size of the CPU cooler that was on my mobo, this would not fit inside, so I opted to mount outside as in the picture. I was worried about the noise at first. But top speed is 800rpm, and the fan is really quiet. Even while gaming it doesnt whine. Also, it comes with an extender cable and rubber corner pads. Im really happy with it.

Set and forget at 700 rpm, at that speed these fans are dead silent, if you go higher they become a little loud.

Only quality product. Likenit was designed by engineers

Just like the headline says. This is the only 200mm fan I bought that had the right screw locations to attach to the top of my HAF XB Evo pc case. Very happy with how it works.
